Thus, a gesture may be detected by detecting a particularcontact pattern. For example, detecting a finger tap gesture includesdetecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) asthe finger-down event (e.g., at the position of an icon). As anotherexample, detecting a finger swipe gesture on the touch-sensitive surfaceincludes detecting a finger-down event followed by detecting one or morefinger-dragging events, and subsequently followed by detecting afinger-up (lift off) event.

FIG. 1B is a block diagram, illustrating exemplary components for eventhandling in accordance with some embodiments. In some embodiments,memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g.,in operating system 126) and a respective application 136-1 (e.g., anyof the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines theapplication 136-1 and applications view 191 of application 136-1 towhich to deliver the event information. Event sorter 170 includes eventmonitor 171 and event dispatcher module 174. In some embodiments,application 136-1 includes application internal state 192, whichindicates the current application view(s) displayed on touch sensitivedisplay 112 when the application is active or executing. In someembodiments, device/global internal state 157 is used by event sorter170 to determine which application(s) is (are) currently active, andapplication internal state 192 is used by event sorter 170 to determineapplication views 191 to which to deliver event information.

In some embodiments, application internal state includes additionalinformation, such as one or more of: resume information to be used whenapplication 136-1 resumes execution, user interface state informationthat indicates information being displayed or that is ready for displayby application 136-1, a state queue for enabling the user to go back toa prior slate or view of application 136-1, and a redo/undo queue ofprevious actions taken by the user.

Event monitor 171 receives event information from peripherals interface118. Event information includes information about a sub-event (e.g., auser touch on touch-sensitive display 112, as part of a multi-touchgesture). Peripherals interface 118 transmits information it receivesfrom I/O subsystem 106 or a sensor, such as proximity sensor 166,accelerometer(s) 168, and/or microphone 113 (through audio circuitry110). Information that peripherals interface 118 receives from I/Osubsystem 106 includes information from touch-sensitive display 112 or atouch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripheralsinterface 118 at predetermined intervals. In response, peripheralsinterface 118 transmits event information. In other embodiments,peripheral interface 118 transmits event information only when there isa significant event; (e.g., receiving an input above a predeterminednoise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173.

Hit view determination module 172 proxies software procedures fordetermining where a sub-event has taken place within one or more views,when touch sensitive display 112 displays more than one view. Views aremade up of controls and other elements that a user can see on thedisplay.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected may correspond to programmatic levels within aprogrammatic or view hierarchy of the application. For example, thelowest level view in which a much is detected may be called the hitview, and the set of events that are recognized as proper inputs may bedetermined based, at least in part, on the hit view of the initial touchthat begins a touch-based gesture.

Hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (i.e., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule, the hit view typically receives all sub-events related to thesame touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which viewor views within a view hierarchy should receive a particular sequence ofsub-events. In some embodiments, active event recognizer determinationmodule 173 determines that only the hit view should receive a particularsequence of sub-events. In other embodiments, active event recognizerdetermination module 173 determines that all views that include thephysical location of a sub-event are actively involved views, andtherefore determines that all actively involved views should rceeive aparticular sequence of sub-events. In other embodiments, even if touchsub-events were entirely confined to the area associated with oneparticular view, views higher in the hierarchy would still remain asactively involved views.

Event dispatches module 174 dispatches the event information to an eventrecognizer (e.g., event recognizer 180). In embodiments including activeevent recognizer deteimination module 173, event dispatcher module 174delivers the event information to an event recognizer determined byactive event recognizer determination module 173. In some embodiments,event dispatcher module 174 stores in an event queue the eventinformation, which is retrieved by a respective event receiver module182.

In some embodiments, operating system 126 includes event sorter 170.Alternatively, application 136-1 includes event sorter 170. In yet otherembodiments, event sorter 170 is a stand-alone module, or a part ofanother module stored in memory 102, such as contact motion module 130.

In some embodiments, application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of data updater 176, objectupdater 177, GUI updater 178, and/or event data 179 received from eventsorter 170. Event handler 190 may utilize or call data updater 176,object updater 177 or GUI updater 178 to update the application internalstate 192. Alternatively, one or more of the application views 191includes one or more respective event handlers 190. Also, in someembodiments, one or more of data updater 176, object updater 177, andGUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from event sorter 170, and identifies an event from theevent information. Event recognizer 180 includes event receiver 182 andevent comparator 184. In some embodiments, event recognizer 180 alsoincludes at least a subset of metadata 183, and event deliveryinstructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. Theevent information includes information about a sub-event, for example, atouch or a touch movement. Depending on the sub-event, the eventinformation also includes additional information, such as location ofthe sub-event. When the sub-event concerns motion of a touch the eventinformation may also include speed and direction of the sub-event. Insome embodiments, events include rotation of the device from oneorientation to another (e.g., from a portrait orientation to a landscapeorientation, or vice versa), and the event information includescorresponding information about the current orientation (also calleddevice attitude) of the device.

Event comparator 184 compares the event information to predefined eventor sub-event definitions and, based on the comparison, determines anevent or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, event comparator 184 includes eventdefinitions 186. Event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2 ), and others. In some embodiments, sub-eventsin an event 187 include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1 ) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begins onthe displayed object for a predetermined phase, a first lift-off (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second lift-off (touchend) for a predetermined phase, in another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across touch-sensitivedisplay 112, and lift-off of the touch (touch end). In some embodiments,the event also includes information for one or more associated eventhandlers 190.

In some embodiments event definition 187 includes a definition of anevent for a respective user-interface object. In some embodiments, eventcomparator 184 performs a hit test to determine which user-interfaceobject is associated with a sub-event. For example, in an applicationview in which three user-interface objects are displayed ontouch-sensitive display 112, when a touch is detected on touch-sensitivedisplay 112, event comparator 184 performs a hit test to determine whichof the three user-interface objects is associated with the touch(sub-event). If each displayed object is associated with a respectiveevent handler 190, the event comparator uses the result of the hit testto determine which event handler 190 should be activated. For example,event comparator 184 selects an event handler associated with thesub-event and the object triggering the hit test.

In some embodiment, the definition for a respective event 187 alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events events do not match any of the events in event definitions186, the respective event recognizer 180 enters an event impossible,event failed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers may interact with one another. In some embodiments, metadata183 includes configurable properties, flags, and/or lists that indicatewhether sub-events are delivered to varying levels in the view orprogrammatic hierarchy.

In some embodiments, a respective event recognizer 180 activates eventhandler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to event handler 190. Activating an event handler 190 is distinctfrom sending (and deferred sending) sub-events to a respective hit view.In some embodiments, event recognizer 180 throws a flag associated withthe recognized event and event handler 190 associated with the flagcatches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-eventdelivery instructions that deliver event information about a sub-eventwithout activating an event handler. Instead, the sub-event deliveryinstructions-deliver event information to event handlers associated withthe series of sub-events or to actively involved views. Event handlersassociated with the series of sub-events or with actively involved viewsreceive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used inapplication 136-1. For example, data updater 176 updates the telephonenumber used in contacts module 137, or stores, a video file used invideo player module 145. In some embodiments, object updater 177 createsand updates objects used in application 136-1. For example, objectupdater 176 creates a new user-interface object or updates the positionof a user-interface obiec. GUI updater 178 updates the GUI. For example,GUI updater 178 prepares display information and sends it to graphicsmodule 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to dataupdater 176, object updater 177, and GUI updater 178. In someembodiments, data updater 176, object updater 177, and GUI updater 178are included in a single module of a respective application 136-1 orapplication view 191. In other embodiments, they are included in two ormore software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput-devices, not of which are initiated on touch screens, e.g.,coordinating joystick or mouse movement and button presses, single ormultiple keyboard presses or holds, user movements taps, drags, scrolls,etc., on touch-pads, pen stylus inputs, movement of the device, oralinstructions, detected eye movements, biometric inputs, and or anycombination thereof, which may be unified as inputs corresponding tosub-events which define an event to be recognized.

Attention is now directed towards embodiments of user interfaces (“UI”)that may be implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu ofapplications on portable multifunction device 100 in accordance withsome embodiments. Similar user interfaces may be implemented on device300. In some embodiments, user interface 400 includes the followingelements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 404;    -   Bluetooth indicator 405;    -   Battery status indicator 406;    -   Tray 408 with icons for frequently used applications, such as:        -   Phone 138, which may include an indicator 414 of the number            of missed calls or voicemail messages;        -   E-mail client 140, which may include an indicator 410 of the            number of unread e-mails;        -   Browser 147; and        -   Video and music player 152, also referred to as iPod            (trademark of Apple Inc.) module 152; and    -   Icons for other applications, such as:        -   IM 141;        -   Image management 144;        -   Camera 143;        -   Weather 149-1;        -   Stocks 149-2;        -   Workout support 142;        -   Calendar 148;        -   Alarm clock 149-4;        -   Map 154;        -   Notes 153;        -   Settings 412, which provides access to settings tor device            100 and its various applications 136; and        -   Online video module 155, also referred to as YouTube            (trademark of Google Inc.) module 155.

FIG. 4B illustrates an exemplary user interface on a device (e.g.,device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tabletor touchpad 355, FIG. 3) that is separate from the display 450 (e.g.,touch screen display 112). Although many of the examples which followwill be given with reference to inputs on touch screen display 112(where the touch sensitive surface and the display are combined), insome embodiments, the device detects inputs on a touch-sensitive surfacethat is separate from the display, as shown in FIG. 4B. In someembodiments, the touch sensitive surface (e.g., 451 in FIG. 4B has aprimary as (e.g., 452 in FIG. 4B) that corresponds to a primary axis(e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance withthese embodiments, the device detects contacts (e.g., 460 and 462 inFIG. 4B) with the touch-sensitive surface 451 at locations thatcorrespond respective locations on the display (e.g., in FIG. 4B, 460corresponds to 468 and 462 corresponds to 470). In this way, user inputs(e.g., contacts 460 and 462, and movements thereof) detected by thedevice on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used bythe device to manipulate the user interface on the display (e.g., 450 inFIG. 4B) of the multifunction device when the touch-sensitive surface isseparate from the display. It should be understood that similar methodsmay be used for other user interfaces described herein.

FIG. 4C illustrates an exemplary adaptive input device for amultifunction device in accordance with some embodiments. In FIG. 4C,adaptive input device 482 includes joystick 486, and two buttons 488-1and 488-2. Adaptive input device 482 is connected with a multifunctiondevice with touch-sensitive surface 451 (e.g., device 100, FIG. 1A) bywired or wireless communication channel 484. For example, adaptive inputdevice 482 may be plugged into external port 124 of multifunction device100. Alternatively, adaptive input device 482 may be connected with themultifunction device using one or more wireless communication protocols,such as Bluetooth or Wi-Fi.

FIG. 4C illustrates exemplary visual indicator 490 displayed on adisplay of a multifunction device with touch-sensitive surface 451(e.g., device 100, FIG. 1A) in accordance with some embodiments. In someembodiments, touch sensitive surface 451 has a primary axis (e.g., 452in FIG. 4C) that corresponds to a primary axis (e.g., 454 in FIG. 4C) ofadaptive input device 482. In this way, user inputs received by adaptiveinput device 482 (e.g., pushing joystick 486 along primary axis 452) maybe used to move visual indicator 490 (e.g., along primary axis 452).Activating a button (e.g., tapping button 488-1 or 488-2) on adaptiveinput device 482 may be used to select or activate a user interfaceobject located at visual indicator 490, which makes the buttonactivation like a tap gesture on the touch-sensitive surface. In someembodiments, when a user pushes joystick 486 while pressing on one ofthe buttons (e.g., 488-1 or 488-2), multifunction device 100 treats suchuser inputs as equivalent to a finger contact moving acrosstouch-sensitive surface 451 at the location of visual indicator 490. Insome embodiments, activating a button will open a menu. It should beunderstood that similar methods may be used for other user interfacesdescribed herein.

Although adaptive input device 482 illustrated in FIG. 4C includesjoystick 486 and buttons 488-1 and 488-2, it should be noted that otheradaptive input devices may be used with the methods described herein(e.g., track balls, hand sticks, mouth sticks, head sticks, and physicalkeyboards). As used herein, an adapitve input device refers to an inputdevice that is configured to receive user inputs without using atouch-sensitive surface. An adaptive input device typically receivesuser inputs representing up, down, left, and right movements, activationevents, and selection events (e.g., equivalent to an activation of abutton or tapping on a touch-sensitive surface) based on a user'smovements, such as hand movements, eye movements, foot movements, headmovements, and/or mouth/tongue movements.

USER INTERFACES AND ASSOCIATED PROCESSES

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that may be implemented on an electronic devicewith a display and a touch-sensitive surface, such as device 300 orportable multifunction device 100.

FIGS. 5A-5AC illustrate exemplary user interfaces for providingaccessibility to a touch-based user interface in accordance with someembodiments. The user interfaces in these figures are used to illustratethe processes described below, including the processes in FIGS. 6A-6Eand 7-13.

FIG. 5A illustrates exemplary user interface 502-A of an emailapplication displayed on touch screen 112 of multifunction electronicdevice 100. User interface 502-A includes display of an email message.Also shown in FIG. 5A is visual indicator 504-1, which corresponds to avirtual touch (e.g., a virtual touch on touch screen 112, such as avirtual single finger contact). Sometimes, the virtual touch is alsocalled a simulated touch (e.g., the device performs as if a finger touchhas been defected at a location of visual indicator 504-1). Visualindicator 504-1 in FIG. 5A is depicted as including a ring.Alternatively, visual indicator 504-1 may include one of: a donut,circle, oval, ellipse, arrow, cross, I-beam, star, or virtual finger(e.g., a finger or hand shaped icon).

Visual indicator 504-1 is configured to move in accordance with an inputfrom an adaptive input device (e.g., 482, FIG. 4C). For example, visualindicator 504-1 may move to a predefined region of touch screen 112(e.g., movement 506-1 of visual indicator 504-1), such as a predefinedcorner of the display, in accordance with the input from the adaptiveinput device. Alternatively, visual indicator 504-1 may moveside-to-side e.g., movement 506-2 of visual indicator 504-1) inaccordance with control (e.g., joystick 486) on the adaptive inputdevice moving side-to-side. In other words, visual indicator 504-1 maymove up, down, left, right, and/or diagonally in accordance with theinput from the adaptive input device.

FIG. 5B illustrates that menu 508 is displayed over user interface 502-Aof the email application. Menu 508 is typically displayed in response toa predefined input from the adaptive input device. For example, menu 508may be displaced in response to visual indicator 504-1 moving to apredefined region of touch screen 112 (e.g., movement 506-1, FIG. 5A, toa corner of the display). As another example, moving the visualindicator 504-1 to a corner of the display followed by activation of abutton (e.g., 488-1, FIG. 4C) on the adaptive input device results indisplay of menu 508. Alternatively, moving visual indicator 504-1side-to-side (e.g., movement 506-2, FIG. 5A) may result in display ofmenu 508. For example, moving the visual indicator 504-1 horizontallyback and forth by at least a predefined distance (e.g., 0.02, 0.03, or0.04 inches) for at least a predefined number of tunes (e.g., 2, 3, or 4times) will open a menu, without needing to activate a button. As yetanother example, activation of a predefined button (e.g., 488-2, FIG.4C) on the adaptive input device may result in display of menu 508. Insome embodiments, when menu 508 is initially displayed, visual indicator504-1 is positioned in a center region of menu 508, as shown in FIG. 5B.In other embodiments, when menu 508 is initially displayed, visualindicator 504-1 maintains its position prior to the display of menu 508.

In some embodiments, menu 508 includes a plurality of icons 510,including one or more of: virtual touches selection icon 510-1, virtualgestures icon 510-2, virtual device icon 510-3, and home button 510-4.In some embodiments, the icons 510 are displayed radially about a centerof menu 508 (e.g., the icons are displayed at a substantially equaldistance from the center of menu 508).

FIG. 5C, visual indicator 504-1 is moved over virtual touches selectionicon 510-1. In some embodiments virtual touches selection icon 510-1 isselected by moving visual indicator 504-1 over virtual touches selectionicon 510-1. In some embodiments, virtual touches selection icon 510-1 isselected by moving visual indicator 504-1 over virtual touches selectionicon 510-1 followed by activation of a button (e.g., 488-1, FIG. 4C) onthe adaptive input device.

FIG. 5D illustrates that menu 512 of virtual multitouch contacts isdisplayed in response to selection of virtual touches selection icon510-4 (FIG. 5C). Menu 512 of virtual Multitouch contacts includes aplurality of icon 514 representing types of virtual multitouch contacts(e.g., two-finger contacts icon 514-1, three-finger contacts icon 514-2,four-finger contacts icon 514-3, and five-finger contacts icon 514-4).In some embodiments, menu 512 of virtual multitouch contacts alsoincludes a single-finger contact icon (not shown). Icons 514 are alsocalled herein virtual multiiouch contacts icons. FIG. 5D alsoillustrates that three-finger contacts icon 514-3 is selected withvisual indicator 504-1.

FIG. 5b illustrates that three visual indicators 504-2, 504-3, and 504-4are displayed in response to selection of three-finger contacts icon514-3 in FIG. 5D. FIG. 5E also illustrates that three visual indicators504-2 dirough 504-4 move to the left (e.g., in accordance with an inputfrom the adaptive input device). It is noted that in some embodiments, athree-finger left-swipe gesture on touch screen 112 displays a userinterface of an open application running on the multifunction device 100(e.g., user interface 502-B of a web browser application) distinct froma currently displayed application (e.g., an email application). In otherwords, the three-finger left-swipe gesture, in some embodiments,initiates navigation to the next open application.

In some embodiments, multifunction device 100 is configured to displaythe user interface of the next open application (e.g., user interface502-B) in response to the leftward movement of the three visualindicators 504-2 through 504-4. In FIG. 5F, user interface 502-B of theweb biovvser application is shown in response to the leftward movementof three visual indicators 504-2 through 504-4. The three visualindicator 504-2 through 504-4 are also shown in FIG. 5F.

FIG. 5G illustates that if no inputs received from the adaptive inputdevice for a predefined time period (e.g., 5 seconds, 10 seconds, 15seconds, or any reasonable time period), display of three visualindicators 504-2 through 504-4 is replaced with display of single visualindicator 504-1. In some embodiments, the predefined time period is setby a user (e.g., via a settings menu, not shown).

In FIG. 5H, like FIG. 5B, the user interface includes menu 508 withvirtual touches selection icon 510-1, virtual gestures icon 510-2,virtual device icon 510-3, and home button 510-4. In FIG. 5H, virtualgestures icon 510-2 is selected with visual indicator 504-1.

FIG. 5I illustrates that menu 516 of virtual gestures is displayed, inresponse to the selection of virtual gestures icon 510-2 (FIG. 5H). Menu516 of virtual gestures includes a plurality of icons 518 representingtypes of virtual gestures (e.g., virtual two-finger pinch/depinchgesture icon 518-1, virtual three-finger swipe up gesture icon 518-2,virtual three-finger swipe down gesture icon 518-3, virtualuser-configured gesture icon 518-4, virtual three-finger swipe leftgesture icon (not shown), virtual three-finger swipe right gesture icon(not shown), virtual four-finger swipe left gesture icon (not shown),virtual four-finger swipe right gesture icon (not shown), virtual fourfinger swipe up gesture icon (not shown), virtual four-finger swipe downgesture icon (not shown), virtual two-finger swipe left gesture icon(not shown), virtual two-finger swipe right gesture icon (not shown),virtual two-finger swipe up gesture icon (not shown), virtual two-fingerswipe down gesture icon (not shown), etc.). As used herein, icons 518are also called virtual gesture icons. It should be noted that virtualgestures icon 510-2 and each virtual gesture icon 518 have distinctfunctions. For example, selection of virtual gestures icon 510-2initiates the display of menu 516 of virtual gestures, and selection ofrespective virtual gesture icon initiates performing an operationassociated with the respective virtual gesture icon. FIG. 5I illustratesthat three-finger swipe up gesture icon 518-2 is selected.

In FIG. 5J, a portion of user interface 502-A and application icon area520 are concurrently displayed in response to the selection ofthree-finger swipe up gesture icon 518-2. Application icon area 520includes a plurality of open supplication icons 5004, each of which,when activated (e.g., via visual indicator 504-1, FIG. 5J), initiatesdisplaying a user interface of a corresponding application.Alternatively, the portion of user interface 502-A and application iconarea 520 may be displayed in response to a three-finger swipe up gestureon touch screen 112.

In FIG. 5K, menu 516 of virtual gestures that includes a plurality oficons 518 (e.g., virtual two-finger pinch/depinch gesture icon 518-1,virtual three-finger swipe up gesture icon 518-2, virtual three-fingerswipe down gesture icon 518-3, virtual user-configured gesture icon518-4, etc.) is displayed. FIG. 5K also illustrates that virtualtwo-finger pinch/depinch gesture icon 518-1 is selected with visualindicator 504-1.

In FIG. 5L, two visual indicators 504-5 and 504-6 are displayed inresponse to selection of virtual two-finger pinch/depinch gesture icon518-1 (FIG. 5K). In some embodiments, the two visual indicators 504-5and 504-6 are visually linked (e.g., with connector 522). In someembodiments, each visual indicator of the two visual indicators 504-5and 504-6 includes a ring-shaped display object. The ring-shaped visualindicator is sometimes called a first-mode visual indicator (as comparedto a second-mode visual indicator, described below with reference, toFIG. 5N).

FIG. 5M illustrates that, in the first mode, the two visual indicators504-5 and 504-6 are moved together in accordance with an input front theadaptive input device. In addition, user interface 502-A is scrolled inaccordance with the concurrent movement of two visual indicators 504-5and 504-6.

In FIG. 5N, two first-mode visual indicators 504-5 and 504-6 arereplaced with two second-mode visual indicators 504-7 and 504-8. Eachsecond-mode visual indicator includes a ring-shaped display object and aconcentric disk-shaped display object. In some cases, the twosecond-mode visual indicators are displayed in response to activation ofa button (e g., 488-2, FIG. 40) on the adaptive input device.

FIG. 5O illustrates that, in response to an input from the adaptiveinput device, the two second-mode visual indicators 504-7 and 504-8 aremoved relative to each other in the second mode (e.g., the distancebetween to second-mode visual indicators 504-7 and 504-8 increases) andthe user interface is magnified (e.g., zoomed-in) accordingly.

In FIG. 5P, menu 508 that includes virtual touches selection icon 510-1,virtual gestures icon 510-2, virtual device icon 510-3, and home button510-4 is displayed. FIG. 5P also illustrates that virtual device icon510-3 is selected with visual indicator 504-1.

In FIG. 5Q, menu 524 of virtual device operations is displayed inresponse to activation of virtual device icon 510-3 (FIG. 5P). Menu 524of virtual device operations includes a plurality of icons 526representing types of virtual device operations (e.g., virtual devicemuting/unmuting icon 526-1, virtual device rotation icon 526-2, virtualdevice shaking icon 526-3, virtual device lock screen icon 526-4,virtual device volume up icon 520-5 virtual device volume down icon526-6, virtual rotation lock icon (not shown), virtual knock-knock icon(not shown), etc.). Exemplary virtual device operations may includeoperations that are normally performed via physical controls on theelectronic device, such as; muting and unmuting the ringer and soundeffects on the device, which is normally performed via a mute switch;locking the device, which is normally initiated via a lock/unlockswitch; increase volume, which is normally performed via a volume upbutton; decrease volume which is normally performed via a volume downbutton. Examplary virtual device operations may also include shaking theelectronic device to perform a predefined operation (e.g., an undooperation) and rotating the electronic device to rotate the displayorientation. Operations like shaking and rotation are typically detectedvia an aceelerometer in the electronic device. As used herein, icons 526are also called virtual device operation icons.

In FIG. 5AB, menu 516 of virtual gestures that includes a plurality oficons 518 (e.g., virtual two-finger pinch/depinch gesture icon 518-1,virtual three-finger swipe up gesture icon 518-2, virtual three-fingerswipe down gesture icon 518-3, virtual user-defined gesture icon 518-4,etc.) is displayed. FIG. 5AB also illustrates that user-defined gestureicon 518-4 is selected with visual indicator 504-1.

In some embodiments, if the user has stored more than one user-definedvirtual gesture, then a menu of at least some of these user-definedvirtual gestures will be displayed in response to selection of customgesture icon 518-4 (not shown). Activation of a particular user-definedvirtual gesture its the menu of user-defined virtual gestures (e.g.,with visual indicator 504-1, not shown) will implement the correspondingoperation. On the other hand, if custom gesture icon 518-4 correspondsto a single user-defined virtual gesture, then the operation thatcorresponds to the single user-defined virtual gesture will beimplemented in response to selection of custom gesture icon 518-4. Forexample, FIG. 5AC illustrates that a predefined operation associatedwith a user-defined virtual gesture is perforated, namely the two-fingervirtual gesture created and stored in FIGS. 5W-5AA. In some embodiments,an animated movement of visual indicators 540-1 and 540-2 is displayedalong with their respective trails 542-1 and 542-2 immediately before,immediately after, or while the predefined operation associated with theuser-defined virtual gesture is performed.

FIG. 6A-6E are flow diagrams illustating a method 600 of providingaccessibility to a touch-based user interface in accordance with someembodiments. Method 600 is performed at an electronic device (e.g.,device 300, FIG. 3, or portable multifunction device 100 FIG. 1) with adisplay and a touch-sensitive surface. In some embodiment the display isa touch screen display and the touch-sensitive surface is on thedisplay. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 600 may be combinedandan the order of some operations may be changed.

As described below, method 600 makes devices wish touch-based userinterfaces accessible to users without fine motor skills in their hands.The method makes it possible for such users to perform operations thatwould otherwise require interaction with the touch-sensitive surface ofthe device.

The device displays (602), on the display, a first visual indicator(e.g., 504-1, FIG. 5A) that corresponds to a virtual touch (e.g. avirtual touch on the touch-sensitive surface, such as a virtual singlefinger contact).

In some embodiments, the first visual indicator comprises (604) one of aring (e.g., 504-1, FIG. 5A), donut, circle, oval, ellipse, arrow, cross,I-beam, star, or virtual finger.

The device receives (606) a first input from an adaptive input device(e.g., joystick 486, button 488-1 or 488-2 in FIG. 4C, or any otheradaptive input devices).

In some embodiments, the first input moves (608) the first visualindicator to a predefined region of the display. For example, moving thevisual indicator to a corner of the display (e.g., a predefined activescreen corner) results in display of a first menu (e.g., movement 506-1,FIG. 5A). As another example, moving the visual indicator to a corner ofthe display followed by activation of a button on the adaptive inputdevice results in display of the first menu.

In some embodiments, the first input corresponds (610) to activation ofa control on the adaptive input device (e.g., activating a physicalbutton, such as a menu button 488-2 in FIG. 4C, on the adaptive inputdevice).

In some embodiments, the first input corresponds (612) to moving acontrol on the adaptive input device from side-to-side (e.g., movingjoystick 486 its FIG. 4C side-top-side, or moving a control on theadaptive input device side-to-side with a body part, such as a hand,eye, foot, head, or mouth).

In some embodiments, the adaptive input device includes (14) a joystick(e.g., 486, FIG. 4C) and the first input corresponds to moving thejoystick from side-to-side.

In response to receiving the first input from the adaptive input device,the device displays (616) a first menu on the display (e.g., menu 508,FIG. 5B). The first menu includes a virtual touches selection icon(e.g., icon 510-1, FIG. 5B). In response to detecting selection of thevirtual touches selection icon, a menu of virtual multitouch contacts isdisplayed (e.g., menu 512, FIG. 5D).

In some embodiments, the first menu includes (618) icons displayedradially about a center of the first menu (e.g., a concentricarrangement about the center). For example, menu 508 in FIG. 5B includesicons 510 displayed radially about a center of menu 508. As additionalexamples, icons in some other menus described herein (e.g., menu 512 inFIG. 5D, menu 516 in FIG. 5I, and menu 528 in FIG. 5R) are displayedradially about a center of the corresponding menu. In addition, icons inmenu 524 in FIG. 5Q may be displayed radially about a center of menu524. This arrangement of icons in the menu makes each icon readilyaccessible.

In some embodiments, a first user interface (e.g., user interface 502-A,FIG. 5A) is displayed (620) on the display immediately prior toreceiving the first input from the adaptive input device, and the firstmenu (e.g., menu 508, FIG. 5B) is displayed over the first userinterface (e.g., as a semitransparent, translucent, or opaque overlay).Similarly, the other menus described herein (e.g., menu 512 in FIG. 5D,menu 516 in FIG. 5I, menu 524 in FIG. 5Q, and menu 528 in FIG. 5R) maybe displayed as semitrasnsparent, translucent, or opaque overlays on anunderlying standard user interface. These overlay menus help makecontrol of the electronic device via the adaptive input device quitesimilar to the control of the device using the standard user interface.

In some embodiments, in response to receiving the first input from theadaptive input device, the device displays (622) the first visualindicator in a center region of the first menu. For example, in FIG. 5R,visual indicator 504-1 is displayed at the center of the menu 508 whenmenu 508 is initially displayed. Displaying the visual indicator at thecenter of the first menu makes each of the options in the first menureadily accessible. Similarly, the visual indicator may be displayedinitially at the center of the other menus described herein (e.g., menu512 in FIG. 5D, menu 516 in FIG. 5I, menu 524 in FIG. 5Q, and menu 528in FIG. 5R) when those menus are displayed in response to input receivedfrom the adaptive input device.

In some embodiments, while displaying a menu on the display (e.g., menu508 in FIG. 5B, menu 512 of virtual multitouch contacts in FIG. 5D, menu516 of virtual gestures in FIG. 5I, menu 524 of virtual deviceoperations in FIG. 5Q, menu 528 of virtual device rotations in FIG. 5R,or any accessible menu), the device constrains (624, FIG. 6B) movementof the first visual indicator such that the first visual indicatorremains on the menu (e.g., to prevent overshoot of visual indicator504-1).

In some embodiments, while displaying the first menu on the display, thedevice receives (626) a second input from the adaptive input device whenthe first visual indicator is displayed off the first menu (e.g.,detecting activation of button 488-1 in FIG. 4C on the adaptive inputdevice when visual indicator 504-1 is located over a display area beyondthe first menu, FIG. 5V); and, in response to the second input, ceasingto display the first menu (e.g., displaying user interface 502-A. FIG.5A). Similarly, the other menus described herein (e.g., menu 508 in FIG.5B menu 512 of virtual multitouch contacts in FIG. 5D menu 516 ofvirtual device rotations in FIG. 5I, menu 524 of virtual deviceoperations in FIG. 5Q, menu 528 of virtual device rotations in FIG. 5R,or any accessible menu) may be dismissed when an input is received fromthe adaptive input device when the visual indicator not over the menu.

In some embodiments, while displaying the first menu on the display, thedevice waits (628) to receive input from the adaptive input device formore than a predefined time period (e.g., 5 second, 10 seconds, 15seconds, or any reasonable time period). In some embodiments, thepredefined time period is set by a user (e.g., via a settings menu). Inresponse to waiting to receive input from the adaptive input device formore than the predefined time period (e.g., without receiving input fromthe adaptive input device), the devicec ceases to display the first menu(e.g., displaying user interface 502-A, FIG. 5A). Similarly), the othermenus described herein (e.g., menu 508 in FIG. 5B, menu 512 of virtualmultitouch contacts in FIG. 5D, menu 516 of virtual gestures in FIG. 5I,menu 524 of virtual device operations in FIG. 5Q, menu 528 of virtualdevice rotations in FIG. 5R, or any accesible menu) may be dismissedwhen input not received from the adaptive input device within apredefined time period.

In some embodiments, the device detects (630, FIG. 6C) selection of thevirtual touches selection icon (e.g., virtual touch selection icon510-1, FIG. 5C). For example, the device detects activation of a button(e.g., 488-1, FIG. 4C) on the adaptive input device when the visualindicator is located over the virtual touches selection icon (e.g.,visual indicator 504-1. FIG. 5C), or detects the visual indicator movingacross the virtual touches selection icon. In response to detectingselection of the virtual touches selection icon, the device displays themenu of virtual multitouch contacts (e.g., menu 512, FIG. 5D). The menuof virtual, multitouch contacts includes a plurality of iconsrepresenting types of virtual multitouch contacts (e.g., two-fingercontact icon 514-1, three-finger contacts icon 514-2, four-fingercontacts icon 514-3, and five-finger contacts icon 514-4 in menu 512,FIG. 5D). In some embodiments, the menu of virtual multitouch contactsalso includes a single-finger contact icon (not shown). The devicedetects selection of a respective virtual multitouch contacts icon inthe menu of virtual multitouch contacts (e.g., detecting selection ofthe virtual three-finger contacts icon 514-2 in FIG. 5D, such as bydetecting activation of a button on the adaptive input device when thevisual indicator is located over virtual three-finger contacts icon514-2 or detecting the visual indicator moving accross the virtualthree-finger contacts icon). In response to detecting selection of therespective virtual multitouch contacts icon in the menu of virtualmultitouch contacts, the device displays one or more second visualindicators (e.g., visual indicators 504-2 through 504-4 in FIG. 5E) thatcorrespond to the respective virtual multitouch contacts icon. In someembodiments, in response to detecting selection of the respectivevirtual multitouch contacts icon in the menu of virtual multitouchcontacts, the device also ceases to display the menu of virtualmultitouch contacts (e.g., menu 512 is not displayed in FIG. 5E). Insome embodiments, the second visual indicators are part of a single iconthat represents multiple contacts that correspond to the respectivevirtual muititouch contacts icon. Therefore, the one or more secondvisual indicators typically move in unison (e.g., moving a same distancein a same direction at a same speed). In some embodiments, the secondvisual indicator are multiple icons that represent multiple contactscorrespond to the respective virtual multitouch contacts icon.

In some embodiments, displaying the second visual indicators includes(632) displaying a number of visual indicators that correspond to therespective virtual multitouch contacts icon. For example, in response toselection of the virtual three-finger contacts icon 514-2 in FIG. 5D,three visual, indicators that correspond to three virtual touches aredisplayed in FIG. 5E. Similarly, in response to selection of the virtualtwo-finger contacts icon 514-1 in FIG. 5D, the device dispUys two visualindicators that correspond to two virtual touches (not shown); inresponse to selection of the virtual four-finger contacts icon 514-3 inFIG. 5D, the device displays four visual indicators that correspond tofour virtual touches (not shown); and, in response to selection of thevirtual five-finger contacts icon 514-4 in FIG. 5D, the device displaysfive visual indicators that correspond to five virtual touches (notshown).

In some embodiment, the device receives (634) a second input from theadaptive input device; and, in response to receiving the second inputfrom the adaptive input device: moves the one or more second visualindicators, and performs an operation in accordance with the movement ofthe one or more second visual indicators. For example, in FIG. 5E,inputs received by pushing the joystick to the left are used to move thethree visual indicators to the left and navigate to a next openapplication, just as if three actual finger contacts were moving to theleft on the touch-sensitive surface.

In some embodiments, while displaying the one or more second visualindicators, the device waits (636) to receive input from the adaptiveinput device for more than a predefined time period (e.g., 5 seconds, 10seconds, 15 seconds, or any reasonable time period); and, in response towaiting to receive input from the adaptive input device for more thanthe predefined time period, replaces display of the one or more secondvisual indicators with display of the first visual indicator. Forexample, in response to waiting to receive input from the adaptive inputdevice for more than the predefined time period (without receiving inputfrom the adaptive input device), the device replaces display of threevisual indicators 504-2 through 504-4 (FIG. 5F) with display of singlevisual indicator 504-1 (FIG. 5G). In some embodiments, the predefinedtime period is set by a user (e.g., via a settings menu, not shown).

In some embodiments while displaying the one or more second visualindicators, the device watts for a user input for a first predefinedtime interval. In accordance with a determination that no user input wasreceived during the first predefined time interval, the device replacesthe display of the second visual indicator with a display of a thirdvisual indicator distinct from the second visual indicator (e.g.,different brightness, different color, different line pattern, differenttransparency, etc.).

In some embodiments, the second visual indicator and the third visualindicator represent the same number of touches.

In some embodiments, while displaying the third visual indicator, thedevice waits for a user input for a second predefined time interval. Insome embodiments, the second predefined time interval is identical tothe first predefined time interval. In other embodiments, the secondpredefined time interval is distinct from the first predefined timeinterval. In accordance with a determination that no user input wasreceived during the second predefined time interval, the device replacesthe display of the third visual indicator with a display of the firstindicator.

In some embodiments, the device displays (638, FIG. 6D) a virtualgestures icon, (e.g., 510-2 in menu 508, FIG. 5H); detects selection ofthe virtual gestures icon; and, in response to detecting selection ofthe virtual gestures icon, displays a menu of virtual gestures (e.g.,516, FIG. 5I). The menu of virtual gestures includes a plurality oficons representing types of virtual gestures (e.g., icons 518, FIG. 5I).The device detects selection of a respective virtual gesture icon in themenu of virtual gestures (e.g., detecting selection of the virtualthree-finger swipe un gesture icon 518-2 in FIG. 5I by activation of abutton on the adaptive input device); and, in response to detectingselection of the respective virtual gesture icon in the menu of virtualgestures, performs an action that corresponds to the respective virtualgesture. For example, in response to selection of the virtualthree-finger swipe up gesture icon 518-2 in FIG. 5I the device displaysapplication icon area 520 that includes a plurality of open applicationicons shown in FIG. 5J. In some embodiments, the device may performactions corresponding to certain gestures without displaying visualindcators that correspond 10 the gestures (e.g., in FIG. 5J, openapplication icon area 520 is displayed without displaying visualindicators that correspond to the three-finger swipe up gesture).

In some embodiments, the device displays (640) a virtual gestures icon(e.g., 510-2 in menu 508, FIG. 5H); detects selection of the virtualgestures icon (e.g., detecting activation of a button on the adaptiveinput device when the visual indicator is located over the virtualgestures icon, or detecting the visual indicator moving across thevirtual gestures icon), and, in response to detecting selection of thevirtual gestures icon, displays a menu of virtual gestures (e.g., 516,FIG. 5I). The menu of virtual gestures includes a plurality of iconsrepresenting types of virtual gestures (e.g., virtual two-fingerpinch/depinch gesture icon 518-1, virtual three-finger swipe up gestureicon 518-2, virtual three-finger swipe down gesture icon 518-3, virtualuser-configured gesture icon 518-4, FIG. 5I). The device detectingselection of a respective virtual gesture icon in the menu of virtualgestures (e.g., detecting selection of virtual two-finger pinch/depinchgesture icon 518-1 in FIG. 5I. such as by detecting activation of abutton on the adaptive input device when the visual indicator is locatedover virtual two-finger pinch/depinch gesture icon 518-1 or detectingthe visual indicator moving across the virtual two-finger pinch/depinchgesture icon); and, in response to detecting selection of the respectivevirtual gesture icon in the menu of virtual gestures, displays a numberof visual indicators that correspond to the respective virtual gestureicon. For example, in response to selection of virtual two-fingerpinch/depinch gesture icon 518-1 in FIG. 5K, two visual indicators thatcorrespond to two virtual touches are displayed in FIG. 5L. The devicereceives a second input from the adaptive input device; and, in responseto receiving the second input from the adaptive input device, performsan operation in accordance with the respective virtual gesture. Forexample, in FIG. 5M, inputs received by the adaptive input device movetwo visual indicators 504-5 and 504-6 and scroll user interface 502-A.In another example, in FIG. 50, inputs received by the adaptive inputdevice display the user interface at a different magnification (e.g., azooming operation).

In some embodiments, in response to receiving the second input from theadaptive input device, the device moves (642) the displayed visualindicators that correspond to the respective virtual gesture to simulatemovement of actual contact on the touch sensitive surface (e.g., in FIG.5M, inputs received by the adaptive input device move the two visualindicators 504-5 and 504-6.

In some embodiments, the device displays (644) a pinch/depinch gestureicon e.g., in the first menu or in a virtual gestures menu; detectsselection of the virtual pinch/depinch gesture icon (e.g., detectingactivation of a button on the adaptive input device when the visualindicator is located over the virtual pinch/depinch gesture icon, ordetecting the visual indicator moving across the virtual pinch/depinchgesture icon); and, in response to detecting selection of the virtualpinch/depinch gesture icon, displays two visual indicators thatcorrespond to contacts in the virtual pinch/depinch gesture. The devicereceives a second input from the adaptive input device; and in responseto receiving the second input from the adaptive input device, performsan operation its accordance with the virtual pinch/depinch gesture. Insome embodiments, while the two visual indicators that correspond tocontacts in the virtual pinch/depinch gesture are displayed, inputsreceived from the adaptive input device are used to perform actions thatcorrespond to an actual pinch/depinch gesture on the touch-sensitivesurface. For example, inputs received by pushing a joystick to the rightare used to move the two visual indicators a part (depinch) and zoom infix display (Conversely , inputs received by pushing the joystick to theleft are used to move the two visual indicatiors together (pinch) andzoom out the display. Thus, a user can use an adaptive input device tooperate an electronic device with a touch-based user interface (e.g.,perform virtual gestures on the display, etc.), even though the userdoes not actually touch the touch-sensitive surface on the device.

In some embodiments, in response to detecting selection of the virtualpinch/depinch gesture icon (e.g., 518-1, FIG. 5K), the device displays auser interface in a first operating mode. The first operating modeincludes displaying a first visual indicator that includes twofirst-mode virtual touch points and a first connector linking the twofirst-mode virtual touch points. While in the first operating mode, thedevice detects a first predefined user input from an adaptive inputdevice (e.g., a selection of a lock button 488-1, FIG. 4C). In responseto detecting the first predefined user input while in the firstoperating mode, the device enters a second operating mode (e.g.,terminating the first operating mode). The second operating modeincludes replacing the first visual indicator with a second visualindicator that includes two second-mode virtual touch points fe.g.,504-7 and 504-8, FIG. 5N), and a second connector linking the twosecond-mode virtual touch points. While in the second operating mode,the device detects a respective user input from the adaptive inputdevice in response to delecting the respective user input while in thesecond operating mode, the device performs a predefined operation (e.g.,a zoom-in or zoom-out operation) that corresponds to a pinch or depinchgesture in accordance with the respective user input, the zoomingoperation is just one example of a predefined operation that may beperformed in response to the virtual pinch/depinch gesture. As anotherexample, in a photo application, a virtual depinch gesture on an albumin a set of albums may result in display of the set of albums beingreplaced with display of digital photos in the selected album (notshown). In turn, a virtual depinch gesture on a photo in the selectedalbum may result in display of the selected album being replaced withdisplay of the selected photo. Conversely, a virtual pinch gesture onthe selected photo may result in display of the selected photo beingreplaced with display of the selected album, in turn, a virtual pinchgesture on digital photos hi the selected album may result in display ofthe digital photos in the selected album being replaced with display ofthe set of albums. More generally, any operation that is performed inthe touch-based user interface by an actual pinch or depinch gesture onthe touch-sensitive surface may also be performed by a virtual pinch ordepinch gesture made with input from the adaptive input device.

In some embodiments, in response to detecting the respective user inputwhile in the second operating mode, the device updates the display ofthe second visual indicator by moving respective locations of the twosecond-mode virtual touch points and adjusting a length of the secondconnector linking the two second-mode virtual touch points (e.g, movingsecond-mode visual indicators 504-7 and 504-8 and connector 522, FIG.5O).

In some embodiments, while in the second operating mode, the devicedetects a second predefined user input from the adaptive input device;and, in response to detecting the second predefined user input while inthe second operating mode, enters the first operating mode (e.g.,terminating the second operating mode). For example, display of thesecond-mode visual indicators in FIG. 5Q may be replaced with display offirst-mode visual indicators. In some embodiments, changing from thesecond operating mode to the first operating mode does not change themagnification of the displayed user interface.

In some embodiments, while in the first operating mode, the devicedetects a second respective user input from the adaptive input device;and, in response to detecting the second predefined user input while inthe first operating, mode, the device scrolls the user interface inaccordance with the second respective user input (e.g., the scrolleduser interface in FIG. 5N).

In some embodiments, each first-mode virtual touch point includes aring-shaped display object (e.g , 504-5 and 504-6 in FIG. 5M); and eachsecond-mode virtual touch point includes the ring-shaped display objectand a concentric circle inside the ring-shaped display object (504-7 and504-8 in FIG. 5N).

In some embodiments, each connector includes a chain-shaped displayobject (e.g., 522, FIG. 5M).

In some embodiments, a zooming operation (e.g., zooming in the displayor zooming out the display) is performed (646) in accordance with thevirtual pinch/depinch gesture (e.g., see the zoomed-in user interface502-A in FIG. 5O).

In some embodiments, the device displays (648, FIG. 6E) a virtual deviceicon (e.g., 510-3 in FIG. 5P); detects selection of the virtual deviceicon, and, in response to detecting selection of the virtual deviceicon, displays a menu of virtual device operations (e.g., menu 524 inFIG. 5Q). The menu of virtual device operations includes a plurality oficons representing types of virtual device operations(e.g., icons 526 inFIG. 5Q). Exemplary virtual device operations may include operationsthat are normally performed via physical controls on the electronicdevice, such as: muting and unmuting the ringer and sound effects on thedevice, which is normally performed via a mute switch; locking thedevice, which is normally initiated via a lock/unlock switch; increasevolume, which is normally performed a volume up button, decrease volume,which is normally performed via a volume down button. Exemplary virtualdevice operations may also include shaking the electronic device toperform a predefined operation (e.g., an undo operation) and rotatingthe electronic device to rotate the display orientation. Operations likeshaking and rotation are typically detected via an accelerometer in theelectronic device. The device detects selection of a respective virtualdevice operation icon in the menu of virtual device operation (e.g.,detecting selection of virtual device rotation icon 526-2 in FIG. 5Q,such as by detecting activation of a button on the adaptive input devicewhen the visual indicator is located over virtual device rotation icon526-2 or detecting the visual indicator moving across virtual devicerotation icon 526-2); and, in response to detecting selection of therespective virtual device operation icon in the menu of virtual deviceoperations, performs an action that corresponds to the respectivevirtual device operation. For example, in response to selection ofvirtual device lock screen icon 526-4 in FIG. 5Q, the device locks thescreen of the device of launches a screen saver application (not shown).Thus, a user can also use the adaptive mnut device to operate thephysical controls on the electronic device, even though the user doesnot actually touch the physical controls on the device.

In some embodiment:, the device displays (650) a virtual device rotationicon (e.g., 526-2 in menu 524, FIG. 5Q); detects selection of thevirtual device rotation icon; and, in response to detecting selection ofthe virtual device rotation icon, displays a menu of virtual deviceorientations (e.g., menu 528, FIG. 5R). The menu of virtual deviceorientations includes a plurality of icons representing types of virtualdevice orientations (e.g., virtual portrait orientation icon 530-1,virtual landscape orientation left icon 530-2, virtual landscapeorientation right icon 530-3, and virtual upside down portraitorientation icon 530-4. FIG. 5R). The device detects selection of arespective virutal device orientation icon in the menu of virtual deviceorientations (e.g., detecting selection of the virtual landscapeorientation left icon 530-2 FIG. 5R, such as by detecting activation ofa button on the adaptive input device when the visual indicator islocated over the virtual landscape orientation left icon 530-2 ordetecting the visual indicator moving across the virtual landscapeorientation left icon 530-2); and, in response to detecting selection ofthe respective virtual device orientation icon in the menu of virtualdevice orientations, orients the display in accordance with therespective virtual device orientation. For example, in response toselection of the virtual landscape orientation left icon 530-2 in FIG.5R, the device changes the orientation of the user interface to thatshown in FIG. 5S.

In some embodiments, the device includes (652) a home button (e.g., avirtual home button displayed on the display or a physical home button204 separate from the display, FIG. 2). The device displays a homebutton icon (e.g., 510-4, in menu 508, FIG. 5T, or in the menu ofvirtual device operations); detects selection of the home button icon(e.g., defecting activation of a button on the adaptive input devicewhen the visual indicator is located over the home button icon, ordetecting the visual indicator moving across the home button icon); and,in response to detecting selection of the home button icon, performs anaction that corresponds to activation of the home button. For example,in response to selection of home button icon 510-4 in FIG. 5T, homescreen 502-D is displayed in FIG. 5U, just as the home button 204 (FIG.2) had been pressed.

Note that details of the processes described above with respect tomethod 600 are also applicable in an analogous manner to the othermethods described herein, including methods 700, 800, 900, 1000, 1100,1200, and 1500 described below. For brevity, these details are notrepeated below.

FIG. 7 is a flow diagram illustrating a method 700 of using a menu ofvirtual multitouch contacts icon in accordance with so me embodiments.Method 700 is performed at an electronic device (e.g., device 300, FIG.3, or portable multifunction device 100, FIG. 1) with a display and atouch-sensitive surface. In some embodiments, the display is a touchscreen display and the touch-sensitive surface is on the display, insome embodiments, the display is separate from the touch-sensitivesurface. Some operations in method 700 may be combined and/or the orderof some operations may be changed.

As described below, method 700 uses a menu of virtual multitouchcontacts in conjunction with input from an adaptive input device (e.g.,a joystick) to select a type of multitouch contact being emulated. Thisenables the user to perform, without using the touch-sensitive surfaceof the electronic device, multitouch operations that would otherwiserequire interaction with the touch-sensitive surface of the electronicdevice using multiple fingers.

The device displays (702), on the display, a first visual indicator thatcorresponds to a virtual touch (e.g., a virtual touch on thetouch-sensitive surface, such as a virtual single finger contact);receives (704) a first input from an adaptive input device (e.g.,detecting activation of a button on the adaptive input device when thevisual indicator is located over the virtual touches selection icon, ordetecting the visual indicator moving across the virtual touchesselection icon); and, in response to receiving the first input from theadaptive input device, displays (706) a menu of virtual multitouchcontacts (e.g. menu FIG. 5D). The menu of virtual multitouch contactsincludes a plurality of icons representing types of virtual multitouchcontacts (e.g., two-finger contacts icon 514-1, three-finger contactsicon 514-2, four-finger contacts icon 514-3, and five-finger contactsicon 514-4 in menu 512, FIG. 5D). In some embodiments, the menu ofvirtual multitouch contacts also includes a single-finger contact icon(not shown).

The device detects (708) selection of a respective virtual multitouchcontacts icon in the menu of virtual multitouch contacts (e.g.,detecting selection of the virtual three-finger contacts icon 514-2 inFIG. 5D, such as by detecting activation of a button on the adaptiveinput device when the visual indicator is located over the virtualthree-finger contacts icon 514-2 or detecting the visual indicatormoving across the virtual three-finger contacts icon); and, in responseto detecting selection of the respective virtual multitouch contactsicon in the menu of virtual multitouch contacts, displays (710) one ormore second visual indicators that correspond to the respective virtualmultitouch contacts icon (e.g., visual indicators 504-2 through 504-4,FIG. 5E). In some embodiments, in response to detecting selection of therespective virtual multitouch contacts icon in the menu of virtualmultitouch contacts the device also ceases to display the menu ofvirtual multitouch contacts. In some embodiments, the second visualindicators are part of a single icon that represents multiple contactsthat correspond to the respective virtual multitouch contacts icon. Insome embodiments, the second visual indicators are multiple icons thatrepresent multiple contacts that correspond to the respective virtualmultitouch contacts icon.

FIG. 8 is a flow diagram illustrating a method 800 of using a menu ofvirtual gestures in accordance with some embodiments. Method 800 isperformed at an electronic device (e.g., device 300, FIG. 3. or portablemultifunction device 100, FIG. 1) with a displays and a touch-sensitivesurface. In some embodiments, the display is a touch screen display andthe touch-sensitive surface is on the display. In some embodiments, thedisplay is separate from the touch-sensitive surface. Some operation inmethod 800 may be combined and/or the order of some operations may bechanged.

As described below, method 800 uses a menu of virtual gestures inconjunction with input from an adaptive input device to select andemulate actual gestures on a touch-sensitive surface, this allows a userto make, without using the touch-sensitive surface of the electronicdevice, virtual multitouch gestures that produce the same results asthose obtained by interacting with the touch-sensitive surface of theelectronic device using multiple fingers.

The device displays (802), on the display, a first visual indicator thatcorresponds to a virtual touch (e.g., a virtual touch on thetouch-sensitive surface, such as a virtual single finger contact);receives (804) a first input from an adaptive input device (e.g.,detecting activation of a button on the adaptive input device when thevisual indicator is located over a virtual gesture, icon, or detectingthe visual indicator moving across the virtual gestures icon); and, inresponse to receiving the first input from the adaptive input device,displays (806) a menu of virtual gestures (e.g., menu 516. FIG. 5K). Themenu of virtual gestures includes a plurality of icons representingtypes of virtual gestures (e.g., virtual two-finger pinch/depinchgesture icon 518-1, virtual three-finger swipe up gesture icon 518-2,virtual three-finger swipe down gesture icon 518-3, virtualuser-configured gesture icon 518-4, FIG. 5K).

The device detects selection of a respective virtual gesture icon in themenu of virtual gestures (e.g., detecting selection of the virtualtwo-finger pinch/depinch gesture icon 518-1 in FIG. 5K, such as bydetecting activation of a button on the adaptive input device when thevisual indicator is located over the virtual two-finger pinch/depinchgesture icon 518-1 or detecting the visual indicator moving across thevirtual two-finger pinch/depinch gesture icon); and, in response todetecting selection of the respective virtual gesture icon in the menuof virtual gestures, displays (810) a number of visual indicators thatcorrespond to the respective virtual gesture icon. For example, inresponse to selection of the virtual two-finger pinch/depinch gestureicon 518-1 in FIG. 5K, two visual indicators that correspond to twovirtual touches are displayed in FIG. 5L.

The device receives (812) a second input from the adaptive input device;and, in response to receiving the second input from the adaptive inputdevice performs (814) an operation in accordance with the respectivevirtual gesture. For example, in FIG. 5M, inputs received by theadaptive input device move, two visual indicators 504-5 and 504-6 andscroll user interface 502-A. In another example, in FIG. 5O, inputsreceived by the adaptive input device displays the user interface at adifferent magnification (e.g., a zooming operation).

FIG. 9 is a flow diagram illustrating a method 900 of performing avirtual pinch gesture in accordance with some embodiments. Method 900 isperformed at an electronic device (e.g., device 300, FIG. 3, or portablemultifunction device 100, FIG. 1) with a display and a touch-sensitivesurface. In some embodiments, the display is a touch screen display andthe touch sensitive surface is on the display. In some embodiments, thedisplay is separate from the touch-sensitive surface. Some operations inmethod 900 may be combined and/or the order of some operations may bechanged.

As described below, method 900 uses two visual indicators (whichcorrespond to two virtual touches) in conjunction with input from anadaptive input device to emulate pinch/depinch gestures on atouch-sensitive surface. This allows a user to perform, without usingthe touch-sensitive surface of the electronic device, an operation(e.g., zooming) that would otherwise require interaction with thetouch-sensitive surface of the electronic device using two fingers.

The device displays (902) a pinch/depinch gesture icon (e.g., in thefirst menu or in a virtual gestures menu); detects (904) selection ofthe virtual pinch/depinch gesture icon (e.g., detecting activation, of abutton on the adaptive input device when the visual indicator is locatedover the virtual pinch/depinch gesture icon, or detecting the visualindicator moving across the virtual pinch/depinch gesture icon); and, inresponse to detecting selection of the virtual pinch/depinch gestureicon, displays (906) two visual indicators that correspond to contactsin the virtual pinch/depinch gesture (e.g., as shown in FIGS. 5K-5L).

The device receives (908) an input from an adaptive input device; and,in response to receiving the input from the adaptive input device,performs (910) a zooming operation in accordance with the respectivevirtual pinch/depinch gesture (e.g., as shown in FIGS. 5N-5O). In someembodiments, while the two visual indicators that correspond to contactsin the virtual pinch/depinch gesture are displayed, inputs received fromthe adaptive input device are used to perform actions that correspond toan actual pinch/depinch gesture on the touch-sensitive surface. Forexample inputs received by pushing a joystick to the right are used tomove the two visual indicators apart (depinch) and zoom in the display.Conversely, inputs received by pushing the joystick to the left are usedto move the two visual indicators together (pinch) and zoom out thedisplay. Thus, a user can use an adaptive input device to operate anelectronic device with a touch-based user interface (e.g., performvirtual gestures on the display, etc.), even though the user does notactually touch the touch-sensitive surface on the device.

FIG. 10 is a flow diagram illustrating a method 1000 of using a menu ofvirtual gestures in accordance with some embodiments. Method 1000 isperformed at an electronic device (e.g., device 300, FIG. 3, or portablemultifunction device 100, FIG. 1) with a display and a touch-sensitivesurface. In some embodiments, the display is a touch screen display andthe touch-sensitive surface is on the display. In some embodiments, thedisplay is separate from the touch-sensitive surface. Some operations inmethod 1000 may be combined and or the order of some operations may bechanged.

As described below, method 1000 uses a menu of virtual gestures inconjunction with input from an adaptive input device to select andemulate actual gestures on a touch-sensitive surface. This allows a userto make, without using the touch-sensitive surface of the electronicdevice, virtual multitouch gestures that produce the same results asthose obtained by interacting with the touch-sensitive surface of theelectronic device using multiple fingers.

The device displays (1002) a virtual gestures icon (e.g., in the firstmenu); detects (1004) selection of the virtual gestures icon; and, inresponse to detecting selection of the virtual gestures icon, displays(1006) a menu of virtual gestures (e.g., as shown in FIGS. 5H-5I). Themenu of virtual gestures includes a plurality of icons representingtypes of virtual gestures.

The device detects (1008) selection of a respective virtual gesture iconin the menu of virtual gestures (e.g., detecting selection of virtualthree-finger swipe up gesture icon 518-2 in FIG. 5I by activation of abutton on the adaptive input device); and, in response to detectingselection of the respective virtual gesture icon in the menu of virtualgestures, performs (1010) an action that corresponds to the respectivevirtual gesture. For example, in response to selection of virtualthree-finger swipe up gesture icon 518-2 in FIG. 5I, the device displaysapplication icon area 520 that includes a plurality of open applicationicons shown in FIG. 5J. In some embodiments, the device may performactions corresponding to certain gestures without displaying visualindicators that correspond to the gestures.

FIG. 11 is a flow diagram illustrating a method 1100 of using a menu ofvirtual device operations in accordance with some embodiments. Method1100 is performed at an electronic device (e.g., device 300, FIG. 3, orportable multifunction device 100, FIG. 1 ) with a display and atouch-sensitive surface. In some embodiments, the display is a touchscreen display and the touch-sensitive surface is on the display. Insome embodiments, the display is separate from the touch-sensitivesurface. Some operations in method 1100 may be combined and/or the orderof some operations may be changed.

As described below, method 1100 uses a menu of virtual device operationsin conjunction with input from an adaptive input device to select andemulate operations that are normally, performed via activation ofphysical controls on the electronic device (e.g., mute switches, lockswitches, volume buttons) or in response to activity detected by anaccelerometer (e.g., device shaking or device rotation). This allows auser to perform operations that would otherwise require interaction withthe physical controls of the electronic device or the device as a whole.

The device displays (1102) a virtual device icon (e.g., in the firstmenu); detects (1104) selection of the virtual device icon, and, inresponse to detecting selection of the virtual device icon, displays(1106) a menu of virtual device operations (e.g., as shown in FIGS.5P-5Q). The menu of vistual device operations includes a plurality oficons representing types of virtual device operations. Exemplary virtualdevice operations may include operations that are normally performed viaphysical controls on the electronic device, such as: muting and unmutingthe ringer and sound effects on the device, which is normally performedvia a mute switch; locking the device, which is normally initiated via alock/unlock switch increase volume, which is normally performed via avolume up button; decrease volume, which is normally performed via avolume down button. Exemplary virtual device operations may also includeshaking the electronic device to perform a predefined operation (e.g.,an undo operation) and rotating the electronic device to rotate thedisplay orientation. Operations like shaking and rotation are typicallydetected via an aecelerometer in the electronic device.

The device detects (1108) selection of a respective virtual deviceoperation icon in the menu of virtual device operations (e.g., detectingselection of virtual muting/unmuting icon 526-1, such as by detectingactivation of a button on the adaptive input device when the visualindicator is located over virtual muting/unmuting icon 526-1 ordetecting the visual indicator moving across the virtual muting/unmutingicon), and, in response to detecting selection of the respective virtualdevice operation icon in the menu of virtual device operations, performs(1110) an action that corresponds to the respective virtual deviceoperation. For example, in response to selection of virtualmuting/unmuting icon 526-1 in FIG. 5Q, the device mutes or unmutes theringer and sound effects on the device. Thus, a user can also use theadaptive input device to operate the physical controls on the electronicdevice, even though the user does not actually touch the physicalcontrols on the device.

FIG. 12 is a flow diagram illustrating it method 1200 of using a menu ofvirtual device orientations in accordance with some embodiments. Method1200 is performed at art electronic device (e.g., device 300, FIG. 3, orportable multifunction deuce 100, FIG. 1) with a display and atouch-sensitive surface. In some embodiments, the display a touch screendisplay and the touch-sensitive surface is on the display. In someembodiments, the display is separate from the touch-sensitive surface.Some operations in method 1200 may be combined and/or the order of someoperations may be changed.

As described below, method 1200 uses a menu of virtual deviceorientations in conjunction with input from an adaptive input device tocontrol the display orientation. This allows a user to orient thedisplay of the electronic device without, physically rotating theelectronic device.

The device displays (1202) a virtual device rotation icon (e.g., in thevirtual device menu), detects (1204) selection of the virtual devicerotation icon; and, in response detecting selection of the virtualdevice rotation icon, displays (1206) a menu of virtual device orientalions (e.g., as shown in FIGS. 5Q-5R) The menu of virtual deviceorientations includes a plurality of icons representing types of virtualdevice orientations (e.g., virtual portrait orientation icon 530-1,virtual landscape orientation left icon 530-2, virtual landscapeorientation right icon 530-3, and virtual upside down portraitorientation icon 530-4, FIG. 5R).

The device detects (1208) selection of a respective virtual deviceorientation icon in the menu of virtual device orientations (e.g.,detecting selection of virtual landscape orientation left icon 530-2 inFIG. 5R, such as by detecting activation of a button on the adaptiveinput device when the visual indicator is located over virtual landscapeorientation left icon 530-2 or detecting the visual indicator movingacross the virtual landscape orientation left icons). In response todetecting selection of the respective virtual device orientation icon inthe menu of virtual device orientations, the device orients (1210) thedisplay in accordance with the respective virtual device orientation.For example, in response to selection of virtual landscape orientationleft icon 530-2 in FIG. 5R, the device orients the user interface ondisplay to that shown in FIG. 5S.

FIG. 13 is a flow diagram illustrating method 1300 of crceting auser-defined virtual gesture in accordance with some embodiments. Method1300 is performed at an electronic device (e.g., device 300, FIG. 3, orportable multifunction device 100, FIG. 1) with a display and atouch-sensitive surface. In some embodiments, the display is a touchscreen display and the touch-sensitive surface is on the display. Insome embodiments, the display is separate from the touch-sensitivesurface. Some operations in method 1300 mav be combined and/or the orderof some operation may be changed.

As described below, method 1300 uses input from an adaptive input deviceto create user-defined, custom virtual gestures. This allows a user torecord and retrieve virtual multitouch gestures that would otherwiserequire interaction with the touch-sensitive surface using multiplefingers.

The device, while in a virtual-gesture recording mode (1302), displays(1304) a plurality of visual indicators on the display (e.g., icons thatcorrespond to respective virtual single finger contacts). For example,in FIG. 5AA, visual indicators 540-1 and 540-2 are displayed.

For each visual indicator in the plurality of visual indicators (1306),the device receives (1308) from an adaptive input device a respectiveuser input for the respective visual indicator; moves (1310) therespective visual indicator in accordance with the respective userinput; and concurrently displays (1312) with the respective visualindicator a respective trail corresponding to movement of the respectivevisual indicator (e.g., visual indicator 540-1 and trail 542-1, FIG.5Y).

In some embodiments, while in the virtual-gesture recording mode, thedevice concurrently displays (1314) the plurality of respective visualindicators and a corresponding plurality of respecti trails. Forexample, visual indicators 540-1 and 540-2 are displayed concurrentlywith trails 542-1 and 542-2 in FIG. 5AA.

The device creates (1316) a user-defined virtual gesture thatcorresponds to the plurality of visual indicators and the movements ofthe plurality of visual indicators. The user-defined gesture may includethe absolute or relative positions of the plurality of visualindicators, and the relative or absolute movements of the plurality ofvisual indicators.

The device associates (1318) the user-defined virtual gesture with apredefined operation of the electronic device; and stores (1320) theuser-defined virtual gesture. Thus, a user can use an adaptive inputdevice to create a custom virtual multitouch gesture for an electronicdevice with a touch-based user interface, even though the user does notactually touch the touch-sensitive surface on the device.

In some embodiments, after creating the user-defined virtual gesture andassociating the user-defined virtual gesture with a predefined operationof the electronic device, the device receives (1322) an input from theadaptive input device (e.g., detecting activation, of a button on theadaptive input device when a visual indicator is located over an iconthat corresponds to the user-defined virtual gesture, such as icon 518-4in FIG. 5AB, or detecting the visual indicator moving across the iconthat corresponds to the user-defined virtual gesture); and, in responseto receiving the input from the adaptive input device, performs thepredefined operation associated with the user-defined virtual gesture.

In some embodiments, in response to receiving the input from theadaptive input device, the device displays (1324) an animated movementof the plurality of respective visual indicators in the user-definedvirtual gesture along their respective trails. For example, in FIG. 5AC,the animated movement of visual indicators 540-1 and 540-2 is displayedalong with their respective trails 542-1 and 542-2. In some embodiments,the stored user-defined virtual gesture includes the location and timeof each visual indicator in the user-defined virtual gesture so thatboth fast and slow user-defined virtual gestures can be recreated,thereby mimicking the exact user-defined Virtual gesture that wascreated in the virtual-gesture recording mode. In some embodiments, theuser-defined virtual gesture can be shown (“replayed”) at a constantspeed, rather than at the speed it was created at in the virtual-gesturerecording mode. Constant speed is useful in cases where it is difficultfor the user to generate events at a “natural pace.” For constant speedvirtual gestures, the events in the gesture may be generated at theaverage rate at which events are received when an actual finger movesacross the touch-sensitive surface, to avoid generating events fasterthan the device can handle them.
